In eukaryotes organisms that possess a clearly defined nucleus the mRNA molecules are more elaborate. The Vascular Highway Introduction Concept 1: The subtle structural difference between the sugars gives DNA added stability, making DNA more suitable for storage of genetic information, whereas the relative instability of RNA makes it more suitable for its more short-term functions.
